2x-2=16x+8-6x
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te 2x+1.
2x-2=10x+8
Pahekotia te 16x me -6x, ka 10x.
2x-2-10x=8
Tangohia te 10x mai i ngā taha e rua.
-8x-2=8
Pahekotia te 2x me -10x, ka -8x.
-8x=8+2
Me tāpiri te 2 ki ngā taha e rua.
-8x=10
Tāpirihia te 8 ki te 2, ka 10.
x=\frac{10}{-8}
Whakawehea ngā taha e rua ki te -8.
x=-\frac{5}{4}
Whakahekea te hautanga \frac{10}{-8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
